Product Description
High temperature calcined alumina is a premium-grade α-Al₂O₃ material produced at over 1600°C for superior crystallinity and thermal performance. It offers high purity, low porosity, and excellent resistance to thermal shock and corrosion, making it ideal for demanding industrial applications such as refractories and technical ceramics.
High temperature calcined alumina powder has high melting point, excellent mechanical strength, hardness, high resistivity and thermal conductivity. It can be widely used in electronic equipment, structural ceramics, refractories, wear-resistant materials, polishing materials and other industries.

FAQ
What is the difference between high temperature and standard calcined alumina?
High temperature calcined alumina is fired above 1600°C to achieve full α-phase conversion, providing superior density and thermal stability compared to standard calcined alumina fired at lower temperatures.
